Champagne Study Guide

History & Key Dates

Early Champagne History

• Gosset: oldest Champagne house still in operation, established 1584 as still wine producer
• Dom Pérignon: monk at Abbey of Hautvillers from 1668; contributions = assemblage (blending) and viticulture
• Division of quality between vin de cuvée and vin de taille: 1718
• Ruinart: oldest sparkling Champagne house, founded 1729

Technical Innovations & House Firsts

• UK's most important contribution to champagne: better glass making (strong English coal-furnace glass, early 17th century)
• Elderberry: used to deepen color of Champagne in the 18th century
• First rosé champagne: "Oeil de Perdrix Mousseux" made by Ruinart in 1764 to Baron von Welzel; first blended rosé champagne by Veuve Clicquot (1777)
• Jean-Antoine Chaptal (1801): French chemist, process of chaptalization named after him. Identified relationship between sugar and fermentation
• Veuve Clicquot Ponsardin (Madame Barbe Nicole Ponsardin): pioneer of remuage/riddling (riddling table developed 1816) AND dégorgement
• André François (1836): pharmacist who measured precise amount of sugar required to induce secondary fermentation without breaking bottle
• Muselet: produced by Adolphe Jacquesson, 1844
• Pommery: first to release Brut Champagne (Brut Nature, 1874)
• Cold disgorging method: invented 1884 by Armand Walfard. Temperature -27°C for frozen plug
• Maillard reaction (1912): needs sugar and proteins for caramel hints. Named after the French chemist
• Salon: first Blanc de Blancs Champagne, 1921. First vintage ever made was 1905 (for private consumption of Eugène-Aimé Salon). First vintage offered for sale was 1921. Purchased by Laurent-Perrier in 1988
• Moët & Chandon: first Champagne house to release tête de cuvée. Dom Pérignon produced in 1921, not released for sale until 1936

Phylloxera

• Phylloxera first discovered in Champagne: 1888 (in the Aube, spread to Marne in 1892)

Organizations & Regulatory Framework

• Syndicat des Grandes Marques: founded 1882, initially 35 houses. Disbanded 1997 (only Bollinger agreed to both claims of quality declaration and quantifiable criteria). Replaced by the Union des Maisons de Champagne (UMC), now representing 370 houses
• AVC (Association Viticole Champenoise/Champagne Viticultural Association): founded 1898 by 23 Champagne Houses. Initial objective: combat Phylloxera
• Fédération des Syndicats Viticoles: created 1904 to suppress wine fraud
• Growers revolted: 1911. Vignerons from southern Aube excluded from region, reinstated in 1927
• Échelle des Crus: established 1911, abolished 2010. Since 2003 no longer used to set grape prices. 100% = Grand Cru, 90-99% = Premier Cru
• 1927: first law setting standards for quality and production methods including permitted grapes
• Setting price of grapes and first regulatory framework: 1935
• AOP introduced in Champagne: 1936 (2009 expansion)
• CIVC (Comité Interprofessionnel du Vin de Champagne): formally established 1941
• ACB (Association des Champagnes Biologiques): created 1998, represents over 180 organic winegrowers and houses
• UNESCO World Heritage "The Champagne Hillsides, Houses and Cellars": received UNESCO status July 2015

Geography, Climate & Geology

Geographic Features

Location & Setting

• Location: Northeastern France, latitude 48N–49.5N; just south of the 50N northern limit for viticulture
• High latitude → marginal climate for grape growing
• Within the Paris Basin: a large downward depression of sedimentary rock strata
• Name origin: Campagna (= open country, unforested land) → Champagne
• 5 Departments: Aisne, Aube, Haute-Marne, Marne, Seine et Marne

Topography

• Open topography ← maritime (Atlantic) influences
• Most vineyards: 90–300 m a.s.l. (many classic sites 100–200 m)
• Côte de Sézanne and Côte des Blancs separated by: Marais de Saint Gonde (site of 1st battle of WWI)

Rivers

• 2 important rivers: Marne and Aube (both tributaries of the Seine)
• Marne banks: Rive Droite / right bank (north, sunnier), Rive Gauche / left bank (south, cooler)
• Aube: flows through the Côte des Bar, which is carved out by the Seine and Aube rivers (Bar-sur-Seine in the west to Bar-sur-Aube in the east)

Climate

• Climate type: Cool continental with maritime (Atlantic) influence
• Average annual temperature: 11°C (low)
• Sunshine: ~1,680 hours/year — relatively low due to latitude and cloudy weather
• Average annual rainfall: 700 mm/yr — adequate for viticulture, spread throughout the year
  • Risks at key stages: flowering & fruit set / disease pressure / harvest (dilution, unhealthy grapes, crop loss)
• Slope planting + sufficient rainfall + chalky soils → maximized sunlight interception → aid ripening → high-quality base wine grapes

Geology & Soil

Paris Basin & Chalk

• Paris Basin: an old seabed — sedimentary rock strata deposited during the Kimmeridgian age
• Thick layers of chalk: chalky soils with limestone subsoil; most common soil type in Champagne (Montagne de Reims, Côte des Blancs)
• Chalk = highly porous limestone (main component: calcium carbonate)
  • Excellent balance of water retention & drainage
  • Steady supply of water even in dry periods; sufficient water to survive while avoiding waterlogging
  • Especially good for Chardonnay → high acid, lean wines with reserved aromatics

Chalk Quality Relationship

• Chalky hillsides in the northern part of Champagne:
  • Planting on slopes + sufficient rainfall + chalky soils → maximized sunlight interception → aid ripening → sufficient water without waterlogging → high-quality grapes for base wine

Two Types of Chalk Soil

• Belemnite chalk: squid-ancestor (belemnite) fossils; primarily on mid-slope and upper slopes; high limestone content; vine roots dig deeply → linked to increased acidity; most Grand Cru villages situated on belemnite chalk
• Micraster chalk: sea urchin fossils; characterizes lower zone, flatter lands

Regional Soil Variation

• Sand and clays: Vallée de la Marne (clay, sand, marl), Côte de Sézanne (mostly clay, pockets of chalk)
• Kimmeridgian marl (limestone + sea fossil): Côte des Bar (Aube) → aromatic, earthy expressions of Pinot Noir
• Topsoil: mostly consists of sand and clay

Dry vs. Wet Champagne

• La Champagne sèche (Dry Champagne): chalk subsoil → dry topsoil → open land; Reims, Épernay, Aÿ, Ambonnay, Verzenay; much of Côte des Blancs
• La Champagne humide (Wet Champagne):
  • Eastern part of the Parisian Basin
  • Subsoil is not chalk but limestone-rich marl
  • Highly fertile, excellent for market gardening but inappropriate for quality sparkling wine production
• La Champagne pouilleuse (Barren/Destitute Champagne): literally "lousy Champagne" — technically dry like Champagne sèche, but too arid and infertile for viticulture
  • Situated to the west of La Champagne humide
  • Chalk soils are fractured and porous → unable to retain moisture → dry, dusty landscape
  • Unfit for viticulture
• La Champagne Viticole (Wine-producing Champagne):
  • Hills rise a further 150–300 m, forming a sheer chain of chalk hills containing the unique belemnite/micraster mix
  • Very thin topsoils of sand, marl, clay, lignite

Crayères (Chalk Tunnels)

• Crayères:
  • Roman chalk tunnels below Epernay and Reims
  • Originally carved as quarries in Early Middle Ages
  • Nicolas Ruinart (founder of Maison Ruinart, the first Champagne house, 1729) aged wines here
  • UNESCO World Heritage Site since July 2015
  • Average internal temperature and humidity: 10–12°C / 90–100% humidity

AOC Zones

• AOC law defines 3 nested zones:
  • Zone de l'Élaboration (647 communes, 600,000+ ha): broadest zone, where vinification, ageing, and transport of Champagne are legally permitted
  • Zone de Production (319 communes, ~300,000 ha): the communes belonging to the appellation, within which AOC grapes may be harvested
    • 2003 INAO revision (requested 2003, validated 2008): production zone expanded from 319 to ~357 communes
  • Zone Parcellaire de Production de Raisins (35,200 ha): the specific delimited parcels, plot by plot, within those communes where AOC vines may actually be planted

Grape Varieties

Permitted Varieties

• 9 permitted varieties (as of August 2025, per Cahier des charges Champagne 2025 decree of 31 July 2025): Arbane, Chardonnay, Chardonnay rosé, Meunier, Petit Meslier, Pinot Blanc, Pinot Gris, Pinot Noir, Voltis

Plantation & Roles

• Plantation percentages: Pinot Noir 38%, Meunier 32%, Chardonnay 30%
• Roles in blending:
  • Chardonnay = elegance and longevity with high acidity
  • Pinot Noir = structure, richness, body
  • Meunier = youthful fruitiness and approachability

Primary Varieties

Pinot Noir

• Pinot Noir in Champagne called: "Précoce" because it ripens early

Chardonnay

• Chardonnay: primary white variety

Meunier

• Meunier: primary alternative to Pinot Noir

Accessory Varieties

• Pinot Gris: traditionally known as Fromenteau in Champagne
• Pinot Blanc: most remaining in Celles-sur-Ource (Aube) where resistance to frost valuable. Cédric Bouchard based here: La Bolorée BdB
• Arbane: used in small quantities
• Petit Meslier: used in small quantities
• Chardonnay rosé: added August 2025 — approved by the French Ministry of Agriculture (Ministère de l'Agriculture et de l'Alimentation) in the revised Cahier des charges
• Voltis: new variety permitted 2022 — the 8th approved variety; first hybrid and first PIWI (Pilzwiderstandsfähige, "fungus-resistant") variety approved in Champagne
  • White grape; Villaris × VRH 3159-2-12 (contains Vitis berlandieri, Vitis rupestris, Vitis vinifera, and Muscadinia genetics)
  • Developed through a PIWI breeding project started in 2000 by INRA (France) and Julius Kühn Institute (Germany)
  • Resistant to downy mildew and powdery mildew
  • Helps reduce use of pesticides, herbicides (banned in Champagne from 2025), and fungicides

Classification System (Échelle des Crus)

Overview

• Échelle des Crus: established 1911, abolished 2010
• Scoring system: 100% = Grand Cru, 90-99% = Premier Cru
• Status change: Since 2003 no longer used to set prices
• Current status: Grand and Premier Crus maintain status with no grape variety restrictions after abolition

Notable Exceptions

• Context: these are fine distinctions under the pre-2010 Échelle des Crus (the percentage-based ranking, now abolished); they no longer affect grape pricing, but the villages retain their Grand Cru / Premier Cru status

• Two 1er Crus rated 99%:

  • Tauxières (Montagne de Reims)
  • Mareuil-sur-Aÿ (Vallée de la Marne)

• 2 villages whose rating differed by grape colour (GC for one colour, 1er Cru for the other):

  • Tours-sur-Marne (GC for red, 1er Cru for white)
  • Chouilly (GC for white, 1er Cru for red)

Viticulture

Planting & Density

• Average planting density: ~8,000 vines/ha (high density)
• Inter-row spacing (between rows): maximum 1.5 m
• Intra-row spacing (between vines in a row): range of 0.9–1.5 m
• Total spacing (inter-row + intra-row combined) must not exceed 2.5 m

Pre-Phylloxera Planting

• En Foule: pre-phylloxera method of planting by provignage/layering. High-density, haphazard layout
  • Bollinger continues in two parcels in Aÿ (Vieilles Vignes Françaises)

Training & Pruning

• Permitted systems:
  • Taille Chablis
  • Cordon de Royat
  • Vallée de la Marne
  • Guyot (single and double)
• Average fruiting buds per vine must not exceed 18 buds per square meter (across all systems)

Taille Chablis

• Best system for Chardonnay; a form of spur pruning with a large proportion of permanent wood
• Typically 3–4 cordons (max 5); at the end of each cordon is a spur with up to 5 buds
• Many cordons → helps protect against frost
• Must be trained to max 0.6 m above the ground → allows ripening fruit to benefit from solar energy (heat and light) reflected from the soil, especially in chalky areas

Cordon de Royat

• Used for Pinot Noir and Meunier
• Single cordon, spur-pruned; shoots are vertically positioned

Guyot

• A replacement cane system with vertical shoot positioning
• Permitted in lesser-rated vineyards for all three varieties; both single and double Guyot

Vallée de la Marne

• Similar to Guyot but with a higher number of buds → mitigate frost risk
• Currently used less frequently than in the past

Harvest Regulations

• Comité Champagne sets harvest dates and yields each year
• Grape samples taken from ~450 control plots starting at véraison (onset of ripening)
• Factors measured: rate of colour change, average grape weight, sugar concentration & acidity, presence of botrytis
• Harvest start dates are set, but individual producers may:
  • Begin harvesting a few days later
  • Apply for derogation from INAO to start earlier if necessary (e.g., to avoid botrytis or lower alcohol levels)

Harvest Practices

• Required by Champagne AOC: whole-bunch pressing and hand harvest
• Hand harvest to avoid crushing, oxidation, and spoilage → preserving fruit quality
• Grapes collected in perforated bins with max capacity 50 kg
• Harvest typically lasts ~3 weeks
• ~1,900 pressing centres across Champagne → minimize transportation time

Yield Regulations

• Purpose: maintain wine quality (avoid over-cropping → dilution of flavour); protect Champagne price & regulate supply and demand
• Higher yields typical for sparkling wine: grapes can be grown at high yields because tannins do not need to fully ripen and flavours/colours do not need to be highly concentrated
• Yields depend on vintage, set by CIVC (Comité Champagne)
• Typical harvest: above 10,000 kg/ha (typically 10,000–12,000 kg/ha)
• In good vintages, a proportion of the crop can be set aside as reserve wines for future needs
• Maximum yields (Rendement de Base): 10,400 kg/ha
• Upper limit by EU law: 15,500 kg/ha
• 2 factors CIVC uses for total harvest yield: maximum press yield and minimum planting density

Recent Yield Limits

• 2020: 8,000 kg/ha (lowest, due to COVID)
• 2021: 10,000 kg/ha
• 2022: 12,000 kg/ha (highest)
• 2023: 11,400 kg/ha
• 2024: 10,000 kg/ha
• 2025: 9,000 kg/ha (lowest in 30 years excluding 2020)

★ 2026 PDX: "What was the lowest yield set in Champagne from 2020 to 2024?" → 2020 (due to COVID)

Viticultural Hazards & Practices

• Chief hazards: frost, mold, hail, winter freeze, untimely rain
• Bouvreux/Boubreux: second crop, rarely ripens, typically left on vine

Winemaking & Production

Primary Method

• Main process: Méthode Champenoise
• Synonyms: Traditional Method, Méthode Traditionnelle, Classic Method, Méthode Classique, Méthode Cap Classique

Whole-Bunch Pressing

• Healthy, uncrushed grapes pressed as whole bunches
• Softer pressing → high juice quality, low phenolics (avoiding extracting tannins from skins and seeds)
• Essential for making white wine from black Pinot Noir and Meunier grapes
• Stems create channels → less pressure needed
• Total pressing limited to 102 L per 160 kg of grapes → prevents over-extraction of phenolics, preserves fruit flavours

Press Types

• Traditional basket press (Coquard): wide and flat → minimizes time juice spends in contact with skins; holds 1 marc (4,000 kg) loaded by hand
  • Maie: the press basin/bottom
• PAI Press (Pressoir à Plateau Incliné): Coquard innovation, automatic tilted press, eliminates manual retrousse
• Pneumatic press: same goal as the traditional basket press

Press Fractions

• Cuvée: first 2,050 L (20.5 hL) per 4,000 kg (1 marc); composed of free-run juice and first pressing
  • Rich in acids; produces wines with great finesse and long ageing potential
  • Before 1992: cuvée was 2,666 L
• Taille: second fraction, 500 L
  • Lower in acidity but richer in colour pigments and phenolics
  • Useful in blends to create wines more expressive in youth; lacks the ageing potential of cuvée
  • More frequently used in non-vintage wines rather than vintage or prestige cuvées
• Rebêche: additional pressed juice; used only for distillation, not for Champagne

Must Settling & First Fermentation

• Must is chilled and allowed to settle → lays foundation for delicacy in the base wine; any astringency or off-flavours would be emphasized by the bubbles
• Chaptalisation: used in cool vintages; becoming less important due to global warming
• Fermentation temperature: typically 14–20°C — retains fruit flavours while ensuring temperature is not too cold for yeast
• Fermentation vessels:
  • Temperature-controlled stainless-steel tanks (most common) → preserve primary fruit & freshness; ease of cleaning
  • Oak: increasing number of quality producers reintroducing oak, especially large oak foudres, for first fermentation → enhances textural richness and mouthfeel
• Champagne barrel size: 205 L (pièce champenoise); 10 barrels from 2,050 L cuvée
• Houses that barrel-ferment base wines: Krug, Bollinger, Jacquesson, Selosse

Yeast Selection

• Cultured yeasts typically used for reliable fermentation in high-acid, low-pH conditions
• Neutral yeasts used to avoid pronounced primary flavours that could compete with autolytic characteristics
• Common to use the same yeast strain for both first and second fermentation
• Yeast for second fermentation must be able to: ferment in alcoholic conditions (~10% ABV), withstand low pH, low temperatures, high pressure, and limited nutrients
• Desirable characteristics for traditional method: rapid autolysis, easy flocculation, good prise de mousse (e.g., EC1118)

Malolactic Conversion

• Optional; converts malic acid → lactic acid
• Reduces and softens acidity; particularly beneficial in cooler years
• Lactic acid gives a creamier texture than tartaric acid
• Diacetyl: produced during MLF but metabolized by yeast during second fermentation → buttery flavour not typically present in finished sparkling wines
• Some winemakers avoid MLF to preserve: house style, acidity in warm vintages / global warming context
• If MLF does not occur during primary stage, risk it could happen during second fermentation → haziness; if undesired, wine may undergo sterile filtration to prevent it
• Houses that avoid malolactic: Alfred Gratien, Krug (most lots but no active prevention), Paul Bara, Gosset (by cuvée), Lanson

Base Wine Requirements

• Minimum potential alcohol: 9%
• Maximum residual sugar: 10 g/l
• Maximum ABV at point of sale: 13%

Secondary Fermentation (Prise de Mousse)

• Second fermentation occurs in the same bottle in which the wine will be sold
• Liqueur de tirage added to base wine, containing: wine and/or must, sugar, cultured yeasts, yeast nutrients, and a clarifying agent (e.g., bentonite or alginate) to facilitate riddling
• For most fully sparkling wines, 24 g/L of sucrose added → creates ~6 atmospheres of pressure and ~+1.5% ABV
  • Sugar to pressure conversion: 4 g sugar creates 1 atm/bar of pressure
• Sugar converted into alcohol and CO₂ by yeast; sugar added at this stage does not affect final sweetness of the wine
• Wine law limits sugar addition to 27 g/L max → 4.9–6 atm of pressure, max increase of 1.5% alcohol
• Tirage timing: may not occur until at least January 1 of year following harvest
• Cuvées historically bottled at lower pressure: Cédric Bouchard (Roses de Jeanne), Roederer Blanc de Blancs, Doyard La Libertine, Pierre Péters Perle du Mesnil, Gimonnet Gastronome, Besserat de Bellefon, Lilbert Perle

Vintage Regulations

• Maximum of year's harvest: 80% may be sold as vintage Champagne
• 100% requirement: 100% of vintage must be in blend if labeled on bottle (with the exception of liqueur de tirage & liqueur d'expédition)

Maturation (Élevage)

• Non-vintage: minimum 15 months in producer's cellar; of which 12 months on the lees
• Vintage: minimum 12 months on the lees; cannot be released until 36 months after tirage; in practice, most vintage wines aged on lees much longer than required
• Cost implications: time on lees increases production costs and market price of Champagne

Bottle Lip Styles (Bague)

• Bague Couronne: thin rounded lip on most bottles, secures crown capsule for 2nd fermentation
• Bague Carré: square-shaped lip securing agrafe (metal staple), indicates cork used for 2nd fermentation. Rare today, associated with traditional/artisan practices, special cuvées
  • Examples: Bollinger (vintage wines, under cork), Henri Giraud (Fût de Chêne, MV Grand Cru, agrafe cork)

Riddling (Remuage)

• Collects the yeast sediment in the neck of the bottle
• Invented by Nicole Barbe Ponsardin (Veuve Clicquot)
• Bottles move from horizontal (sur latte) to inverted (sur pointe)
• By hand: "A"-shaped racks (pupitre) holding 120 bottles (60 each side); labour-intensive, skilled work; ~3 months (odd-shaped and premium bottles)
  • Pointage: briskly shaking each bottle to prevent sediment sticking. Newer yeast strains preclude need; most houses abandoned
• Gyropalette: automated; 504 bottles; less labour, skill, and space required; 3–4 days

Disgorgement (Dégorgement)

• Removing dead yeast sediment from the bottle

Methods

• À la glace (freezing): neck of bottle placed into icy brine solution (~−7°C) → freezes yeast into an ice plug; bottle turned upright, crown cap removed, pellet of frozen yeast flies out under pressure
• À la volée (traditional hand method): disgorging without freezing; wine ejected by its own pressure while bottle is inverted
• Transvasage (transfer method): bottle-fermented wine is emptied under counter-pressure (isobaric) into a pressurised tank, filtered to remove the lees, then rebottled — replaces riddling/disgorgement for formats that are hard to riddle (small splits and large formats)
  • In Champagne: max 20% of NV half bottles (375 ml) may undergo transvasage

★ 2023: "What does disgorgement à la volée mean?" → Disgorging without freezing; wine ejected by its own pressure while inverted (traditional hand method)

Liqueur d'Expédition (Dosage)

• Composition: wine + sugar (known as dosage) or RCGM (rectified concentrated grape must)
  • MCR (Moût concentré et rectifié / RCGM): concentrated and rectified grape must, increasingly preferred by small growers for dosage
• Used to top up bottle after disgorgement (where some wine may have escaped)
• Determines the sweetness of the final wine
• Dosage balances the wine's acidity
• Aged wine → less dosage needed (perception of acidity naturally softens with age)
• Young wine → more dosage; dosage also accelerates Maillard reaction
• Maillard reaction: needs sugar and proteins for caramel hints. Named after French chemist (1912)
• Growing trend toward Brut Nature (no dosage) and Extra Brut (<6 g/L)

Jetting & Final Corking

• Post-disgorgement sequence: (1) Disgorgement → (2) Dosage (liqueur d'expédition) → (3) Jetting → (4) Final corking + muselet
• Jetting:
  • Micro-spray of liquid — usually wine, sometimes water with sulfites (varies by producer/equipment)
  • Done immediately before final corking; bottle sealed while O₂ is at its minimum
  • Creates foam expelling oxygen from headspace
  • Reduces O₂ to <0.5 mg/L
  • Can reduce SO₂ in liqueur d'expédition by ~30%
  • Practiced by Ruinart, Bollinger

★ 2024: "Which flavor does Bollinger try to limit with high humidity in cellars and jetting?" → Oxidation (and possibly bitterness)

★ 2026 Korea: "What are the two processes that occur before and after jetting in the méthode champenoise?" → Disgorgement (before) and final corking with muselet (after)

Reserve Wines for Blending

• Larger houses have capacity to store large quantities of different reserve wines → reduces risk from disease, frost, or hail affecting a particular year's harvest
• Key to creating consistent house style:
  • Typically 10–15% of reserve wines (from last 1–2 vintages) used by many large brands
  • Premium brands may use 30–40% of older wines to add depth and complexity
• Storage methods:
  • Stainless steel containers: commonly used for larger volumes; preserves freshness, contributes subtle complexity
  • Old oak barrels: can impart mildly oxidative notes
  • Magnum bottles: unusual method (e.g., Bollinger)
  • Réserve Perpétuelle: see below
• Réserve Perpétuelle: inspired by Spanish Solera. Base vintage isolated, each year new harvest wine added. Good for smaller producers' space issues. Adds complexity to NV wine, maintains house style
  • Two methods:
    • (1) Solera-inspired (blending across years in single vessel)
    • (2) Single container tank method
  • Producers: Jacques Selosse, Bonnet-Ponson, Mathelin, Robert Moncuit, Henri Giraud, Dehours & Fils, Maurice Grumier
  • Not used for Vintage Champagne: must be 100% grapes from stated year

★ 2025: "What are the two methods used to produce Reserve Perpétuelle in Champagne production?" → Solera-inspired Réserve Perpétuelle and single container tank method

★ 2025: "Why does vintage Champagne not use reserve perpetuelle?" → Vintage Champagne must be made from 100% grapes harvested in the stated year

★ 2026 PDX: "Which producer uses solera wines as base wines (Selosse, Gimonnet, Agrapart, ...)?" → (Jacques) Selosse

• Remise en cercle(s) ("return to hoops"): un-bottling Champagne that has already undergone its second fermentation and sending it back into a tank to be re-blended, aged, or corrected — potentially followed by a fresh ("second-second") fermentation. Name refers to the hoops around a wooden cask; the wine is "put back in the circle"
  • Original purpose (corrective): a salvage move when the second fermentation failed — bottles reopened, reworked (often blended with younger vins clairs or reserve wine), then re-fermented
  • Modern corrective use: reset freshness/typicity by blending shelf-aged or prematurely oxidative bottles back into a fresh base. Thiénot buys back bottles showing premature oxidation and reintegrates them into the reserve base
  • Complexity use: a distinct form of assemblage — blending wines that have already completed a full second fermentation, adding a "3D layering" of depth (advocated by Laurent Hostomme)
  • Volume/reserve use: large houses (e.g., Nicolas Feuillatte) buy in profile-matching bottles, correct, and reintegrate "in medicinal doses" to meet demand and build reserve
  • Prestige examples: Pierre Péters "Héritage" (remise en cercle from vintages back to 1921) → base of Fleur de Miraval ER1; Moët & Chandon MCIII (incorporates 1999/1998/1993 remis en cercle)
• Quart de mousse (cousin technique, ≠ remise en cercle): a low-pressure "quarter" fermentation — just enough CO₂ to protect reserve wine from oxidation without full sparkle; aged in magnums for slow micro-oxygenation (e.g., Bollinger, Lenoble, Hautbois)
  • Method: a reduced-dose liqueur de tirage (small amount of sugar + yeast, roughly a quarter of a full tirage) is added before bottling → a partial second fermentation ("micro-champagnisation") generates only ~1/4 of normal pressure (vs ~24 g/L → 6 bar for full mousse)
  • Per Terre de Vins, Bollinger gives its reserve magnums a low-pressure tirage of ~1.4 bar; the wine is later transferred back to a cuve, assembled, then given a new tirage and a new in-bottle second fermentation

Five Districts (North to South)

Montagne de Reims

• Primary grape: Pinot Noir (PN > CH >> PM)
  • Among Grand Crus, only Sillery has a higher proportion of Chardonnay than Pinot Noir
• Topography: more of a wide plateau than a mountain
• Geography: Vineyards divided between south and north-facing slopes. Plain beneath northern Montagne too cold, but higher slopes enjoy warm air pocket
  • Some top villages face north → excellent cool-climate sites but more prone to frost
  • North-facing Grand Crus: Verzenay, Verzy, Mailly (thanks to "Thermal Zone")
• Soil: chalky soil in Grand Cru villages → good balance of water retention and drainage
• Wine style: very high acidity & austere in their youth
• Grand Crus (9): Ambonnay, Beaumont-sur-Vesle, Bouzy, Louvois, Mailly, Puisieulx, Sillery, Verzenay, Verzy
• Premier Crus: 25 total

Subzones of Montagne de Reims

• Massif de Saint-Thierry: Pinot Meunier dominant; right bank of River Vesle, northwest of Reims; northernmost vineyard area in Champagne; vineyards mostly southeast-facing
• Monts de Berru: Chardonnay dominant; 7 km east of Reims; vineyards surround Mont Berru in various aspects; chalk soils
• Vesle and Ardre Valleys (Val de Reims):
  • Pinot Meunier dominant
  • South of Massif de Saint-Thierry, west of Reims
  • Vineyards on both banks of River Ardre — right bank vineyards situated between River Vesle and River Ardre
  • Northeast- or southeast-facing
  • Sand, clay, marl soils
• Grand Montagne de Reims:
  • Pinot Noir dominant
  • Horseshoe-shaped elevated terrain, south of Reims and north of Épernay
  • Vineyards face south, east, northwest, and north depending on village
  • Soil varies by village — limestone-rich marl or chalk
  • Grand Cru villages are located here

Vallée de la Marne

• Primary grape: Pinot Meunier — later budding and earlier ripening than PN & CH → well-suited for frost-prone areas
  • Chardonnay also grown here; used to blend early-drinking wines
• Topography & Location: west of Épernay; valley formed by the River Marne flowing westward toward Paris; frost-prone valley terrain
• Soil: clay, marl, and sandy soils → producing fruity wines; some chalk where CH and PN are grown
• Wine style: fruity, approachable
• Grand Crus (2): Aÿ, Tours-sur-Marne — Grand Cru vineyards here are primarily Pinot Noir
• Premier Crus: 8 total

Producer Types

Classification System

• Matriculation number: code assigned by CIVC, preceded by 2 initials indicating producer type (the codes below)

Producer-Type Codes

• NM (Négociant Manipulant): purchases grapes and/or base wines to produce Champagne; may also use own-grown grapes. Most large Champagne houses are NM
  • e.g. Moët & Chandon, Krug, Veuve Clicquot, Mercier, Ruinart (LVMH group); Pommery, Jacquesson, Billecart-Salmon
• RM (Récoltant Manipulant): grower-producer; makes Champagne from grapes grown in own vineyards. 95% grapes from own vineyards
  • Examples: Jacques Selosse, Egly-Ouriet, Pierre Péters, Vilmart & Cie
• RC (Récoltant Coopérateur): individual co-operative member; shares facilities at a co-operative cellar but wines are sold under the individual grower's own label
• SR (Société de Récoltants): registered firm of 2+ growers who produce together; may sell under one brand or several
  • Examples: Guy Charlemagne (Le Mesnil-sur-Oger)
• CM (Coopérative Manipulant): co-operative cellar; members produce specific wines together under the co-operative brand. ~1,200 members across ~100 cooperatives
  • Examples: Mailly Grand Cru, Jacquart, Nicolas Feuillatte
• MA (Marque d'Acheteur): Champagne sold under a buyer's own label (e.g., restaurant, supermarket, wine shop); the wine can originate from any producer type (NM, RM, CM, etc.)
  • Example: Duperrey (made by G.H. Martel & Co for retailer own-label)
• ND (Négociant Distributeur): buys finished Champagne and distributes under own label

Recent Trends

• Neo-négociants (shifted from grower): Savart, Vilmart, Bérêche, Jerome Prevost, Emmanuel Brochet
• In 2018: grower champagne lost 120 producers

Wine Business

Ownership & Land Restrictions

• Contrôle des Structures: prohibits any firm from farming more than 15 owned or rented hectares (why merchant houses own just over 10% of vineyards)
• Largest landowner: Moët et Chandon, 1,190 ha (nearly 10% of region)

Inventory & Market Management

• Current inventory: ~1.285 billion bottles (~4.8 years supply)
• Target inventory: 4.2 years
• Reduction reasons: oversupply, global economic slowdown, price defense strategy, US tariff risks (10% of exports, 14% of revenue)
• Blocage/déblocage: reserve and release of wine stocks for future vintages

Brand & IP Protection

• Russia 2021: Putin rules that French Champagne can only be sold as "sparkling wine" in Russia; only Russian "shampanskoye" can use that term

Market Distribution

• Champagne percentage of all sparkling wine: ~8–10%
• Grower champagnes percentage of market: less than one quarter
• Average RM production: ~18,000 bottles/year
• Largest markets for Champagne: UK, USA, Germany, Japan
